LINQ Canonical Functions and Oracle Functions

Hello,
I am using EntityFramework (.NET 4) to access a Oracle Database (11g Express Edition Release 11.2.0.2.0 - 64bit Production).
For the most part it is working fine, but now I've stumble into a issue using LINQ Canonical Functions, that aparently are supported (see : Mapping LINQ Canonical Functions and Oracle Functions)
I am running the following expression :
var expirationDuration = 3000;
var record = Context.Table
.Where(x => x.Created.AddMilliseconds(expirationDuration) > DateTime.Now )
.FirstOrDefault();
And im getting a exception :
"LINQ to Entities does not recognize the method 'System.DateTime AddMilliseconds(Double)' method, and this method cannot be translated into a store expression."
Shouldn't AddMilliseconds be translated to (expression) + INTERVAL like the docs mentions?
Thanks for help
Regards,Nuno

Neither ODP.NET nor SQLClient recognizes System.DateTime AddMilliseconds(Double) method as a valid method
I would suggest you use EntityFunctions AddMilliseconds instead.

Need a function name for Sql and Oracle

Retrieving value of next line by doing opteration in previous row.

Can you rephrase the question? Or better yet, provide an example? I'm not sure I understand what you are asking.
My best guess is that you are looking for the analytic functions LEAD or LAG in Oracle, assuming you are on a relatively recent Oracle version. If by "SQL and Oracle" in your subject you mean "SQL Server and Oracle" (SQL is a language that all relational databases implement, SQL Server is Microsoft's relational database), I have no idea how (or if) you can do something similar with a built-in function in SQL Server. You would want to post in a SQL Server group to see how they handle that sort of thing.

We have a Canon SX40Hs and cannot activate the digital zoom function. can you help?Thanks

We have a Canon SX40Hs and cannot activate the digital zoom function. I have tried changing the mode from Auto to "P" to "Tv" etc and the dig zoom function is greyed out and not accessible. Any help?
Thanks

Actually, this is a friend's camera, but yes, I went to the menu and when I got to the digital zoom option, it is greyed out (not accessible). That is the problem. I shoot in the EOS line so figured maybe there was a custom function somewhere that was causing the problem, but Power shot line apparentley doesn't have custom functions. Thought maybe digital zoom is only availabel in certain modes (pernaps not available in "green square"), but changing mode didn't seem to make it accessible either. I am just not familiar with the powershot cameras so ... any other suggestions?

What is the difference between Open-Script and Oracle functional testing

Hi All,
Please help me in spotting out the difference between the Openscript and Oracle Functional Testing for Web Application.
Does Oracle Functional Testing for Web Application have any special features when compared with Open-Script.
Please help me out.
Thanks in Advance,
Nishanth Soundararajan.

OFT is the old version of OpenScript, which will no longer be part of ATS as per the next major realize 9.20.
I would recommend to to spend any time looking at it.

Oracle Single Sign on and Oracle Internet Directory

Hello Gurus,
What is the relationship between Oracle Single Sign on and Oracle Internet Directory.
To my understanding, OID is required to install SSO.
If OID already exist, can we just install SSO and go on integrating it to existing OID.
Great Thanks,

Hi Tim,
I've been working on this and could reproduce the issue with anonymous binds. A fix will be ready in 4.2.1.
So what I really need is the password used for login to pass to the is_member call.The P101_PASSWORD item does not save state. However, you can access the value during submit processing of the login page, for example in the post authentication function of your authentication scheme. People sometimes put code in there to query the user's groups (e.g. with apex_ldap.member_of2) and save them in an application. This item value can then be used in the authorization schemes.

Christian

Oracle Spatial and Oracle Forms

Hi,
Does anyone have experience with Oracle Spatial and Oracle Forms?
I have generated a form, which is based on a view. The view uses the mdsys.sdo_relate operator. Somehow I am unable to get the form to perform (to get one record it takes over 20 minutes). While useing sql-navigator to process the same statement it seems no problem. The query that also uses the view, is then processed in 10 seconds.
I also noticed that when text-functions like ' lower' of ' upper' are used to query the view, the query is processed within 15 seconds. If I don't use ' lower' or ' upper' it takes a long time (> 20 minutes) to process the query. Is it possible that this causes the bad performance of the form?
On metalink I have found that forms and spatial do not cooperate because of the pl/sql version that
forms6 uses. There is no solution presented, does anyone know of a work around?
My configuration is:
Oracle 8.1.7 on WIN2K @ PIII-800Mhz 256 Mb memory.
Formsbuilder 6
If requested I can post the queries that I have made.
With regards,
Gerjan Walrecht

Limitation on SQL executing select statement from ADO and Oracle 8.1.7.1 OleDB Driver

Hi,
we are running a query with a big dunamic select statement from VB code using ADO command object. When Execute method is called system hangs and control won't return back to the application. it seems to be that there is some type limitation on Query string length. Please tell us if there is any?
we are running Oracle 8.1.7 Server on Windows 200 Server and connecting from a W2K professional, ADO 2.6 and Oracle OLEDB 8.1.7.1 OLEDB Driver.
Sample code:
Dim rs As ADODB.Recordset
Dim cmd As ADODB.Command
Set cmd = New Command
With cmd
.CommandText = ' some text with more than 2500 characters
.CommandType = adCmdText
Set rs = .Execute
End With
when i debug using VB6 and when .Execute line is called system hangs or return a message method <<somemethod> of <<some class name>> failed error.
Any help is appreciated.
Thanks,
Anil

A stored procedure would only slow you down here if it was poorly written. I suspect you want to use the translate function. I'm cutting & pasting examples from the documentation-- a search at tahiti.oracle.com will give you all the info you'll need.
Examples
The following statement translates a license number. All letters 'ABC...Z' are translated to 'X' and all digits '012 . . . 9' are translated to '9':
SELECT TRANSLATE('2KRW229',
'0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ',
'9999999999XXXXXXXXXXXXXXXXXXXXXXXXXX') "License"
FROM DUAL;
License
9XXX999
The following statement returns a license number with the characters removed and the digits remaining:
SELECT TRANSLATE('2KRW229',
'0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ', '0123456789')
"Translate example"
FROM DUAL;
Translate example
2229
Also, LIKE '%<string>%' is going to be rather expensive simply because it has to compare the entire string and because it forces full table scans, rather than using indexes. You could speed this sort of query up by using interMedia Text (Oracle Text now in 9i). If you can eliminate one of the '%' options, you could also improve things.
My guess is that your stored procedure is inefficient and that's causing the problem-- 5k rows per table should be pretty trivial.
If you post your query over on the PL/SQL forum, there are better performance tuners than I that might have more hints for you. To get really good advice, though, you'lllikely have to get at least the execution plan for this statement and may need to do some profiling to identify the problem areas.

Reports from Java and Oracle database

Hi
I need to generate couple of reports from my application, with Java as front end and oracle 11.2.0.3.0. database . Reports are having very simple select statements, using the criteria users enter from GUI. we don't need to execute a direct select statement from Java, with the where clauses . I did some research and found out about Pipelined functions. I tested for a small set of records and it worked fine. Will this work for large data set? any drawbacks of using this method? Any other methods for this requirement?
Thanks in advance
JP

Pipeline table functions do not sound like the appropriate approach. It is designed to primarily deal with data transformations. Using it as a rendering engine for report writing? There are fundamental problems with such an approach.
As Dave and Andre commented - the CORRECT means for PL/SQL to pass "data" to Java (or other client languages) is via reference cursors (pointers that the client can use for referencing SQL cursor programs on the server). And Java as a report writer does not really compare with the ease and flexibility that Oracle Apex (Application Express) provides as a reporting framework.

Canon FS10 and importing into FCE

I have a Canon FS10 and want to import the footage but can't figure out which Easy Setup setting to use. I can import in iMovie 08 easily, but do not want to go through the hassle of two programs.
Has anyone used any of the Canon FS line with FCE?
Please help.
Brett

I bought the Canon HF10 - loved it and then was only able to download into iMovie. Being a fan and active user of FCE, I bit the bullet and upgraded from 3.0 to 4.0. Went to the Caymans came home to download using 4.0 and the Log and Transfer function failed to capture the clips as promised. Then I read that I needed to install the update to FCE 4.0.1. I did the update and wallah the import using the Log and Transfer worked. But a few cautions - its slow transfer, I miss firewire. Second, you have to wakeup the camera connection to the Mac, I found command+8, woke it up and the clips showed up in the window. I ignored all the error messages about the directory structure.

Forms 4.5 and Oracle 8i

Hello,
we want to upgrade from Oracle 7.3 to Oracle 8i and we still want to use Forms 4.5.

Oracle v7 and Oracle 9i Release 2

Hi,
Does anyone know a way to allow both database to communicate with each other? Assuming that both of time are residing in a separate machine and Oracle v7 is hosted in HP-UX and Oracle 9i is hosted in Windows 2003.
thanks.

Thanks. :)
So what kind of solution do you propose if i want my v7 to talk to 9i Rel 2? i would like to upgrade one of the DB to 9i and still retain the function. currently, the function is to fetch data from one DB to the other using DBLink. So if i upgrade one of them to 9i, then this option will not be available.
i m thinking of creating an application to act as a medium between v7 and 9i so that whatever PL/SQL that go over to 9i, will be intercepted by this application and the latter will fetch the data from 9i and transmit back to v7. the connection between v7 and the application will be ODBC/JDBC depending on what language the application is developed in.
What does everyone think about it?
cheers

Conflict between oracle 8 and oracle 11

Hi,
I'm having a problem installing oracle 8 and oracle 11 homes at the same time. It looks like the system can only recognize one of the homes. I have 2 different applications running in the same computer. One of them uses oracle 11 and the other oracle 8. The problem is, the one with the oracle 8 can't recognize it, and tries to use the 11, saying it doesn't support the connection. I've checked the registry info and it looks like there is only one Home specified. Should I create a new one? More over, when i use the home selector it says there's only one home available.

Yea they are, I even tried to use a script similar with:

cd "app_folder"
app.exe

to make sure the variable with be the correct when we tried to open the application. I can use the application linked to the oracle 11 but, when i try to get in the other it gives me the following error:
The procedure entry point orasql10.sqlxss could not be located in the dynamic link library orasql8.dll.When you change the environment variables in a command line window (run cmd.exe), the changed variable values only exist in that command line window, but those environment variables are inherited by other programs started from the command line window. If the Oracle 8i client is normally listed first in the PATH environment variable, and you want to execute another program that requires the 11g client, you will need to repeat the above steps for the second program.
You can use a program named Dependency Walker to see which DLL files will be accessed by a program (or even a DLL such as ORASQL10.DLL). In the case of a DLL, you would be able to determine if a specific function name sqlxss (ordinal 183 in this case) exists in that DLL. The Dependency Walker program typically ships with Microsoft's development environments. You can find out more about that program here:

"Oracle BPM Suite 11g" and "Oracle SOA Suite 11g" components

Dear Friends,
I am very confusing about the "Oracle BPM suite 11g" and "Oracle SOA Suite 11g" and would like your help on explanation as the following :
I have learn that In order to use "Oracle BPM Suite 11g" require to have "Oracle SOA Suite 11g" components to install first. Does it means that :
1) When we buy "Oracle BPM Suite 11g" , we automatically get the "Oracle SOA Suite 11g" components as well ?
2) IS it correct that these " these Oracle SOA Suite 11g components" are included :
(a) Oracle BAM
(b) Oracle Business Rules
(c) Oracle BPEL Manager
(d) Oracle Service Bus
(e) Oracle Complex Event Processing
3) Do we have a right to use all of these components listed in (2) ?
4) Then the answers in (3) is "YES", then Is it correct when the customer buy the "Oracle BPM Suite 11g" , they no need to buy "Oracle SOA 11g" any more when they would like to implements that applications based on SOA in the future (without using BPM) ?
5) What IF , the customer would like to start with "Oracle SOA Suite 11g" product and decide to buy only Oracle SOA Suite 11g first ; then later on in the future they would like to implement BPM projects in the future. Can you upgrade "Oracle SOA Suite 11g" to include "Oracle BPM Sutie 11g" and pay only the price different ?
I hope you can help providing the answers to these questions. THank you very much in advance.
Best Regards
Pearapon S.

This is a question best answered by your Oracle reseller or Oracle account manager to give you all the details but I hope this brief answer helps:
- The Unified Business Process Management Suite (BPM Suite 11g) includes: BPM Studio, BPM Composer, BPMN Service Engine and Workflow Extensions, BPM Process Spaces, and BPM Process Analytics.
- BPM Suite 11g requires the licensing of SOA Suite 11g for Oracle Middleware which requires a license for WebLogic Suite.
- You can license SOA Suite 11g now and license BPM Suite 11g later.
Since the products are layered, I don't see this cutting into SOA sales at all. My personal view is that BPM on top of SOA is brilliant since it provides easy integration between human and automated tasks, builds on many of the SOA concepts that are key for a successful BPM implementation (functional, not the Oracle product), and uses the same IDE. The synergies extend past easy use of services; the same business rules and human workflow components are used between both products.

Date Formats in Oracle Applications Forms and Oracle Self Service

Can someone tell me what determines the Date format that appears on Oracle Applications Forms and Oracle Self Service ?
*1.* In Oracle HRMS,all dates i see on the Forms are of the Format "MM/DD/YYYY" but my NLS Parameters are not in this format .I'm giving the results for the NLS parameters below.I thought the date formats are determined by the NLS format.Is there something else that determines the date format appearing on Oracle Applications Forms ?
NLS_DATABASE_PARAMETERS
NLS_DATE_FORMAT     :DD-MON-RR
NLS_DATE_LANGUAGE     :AMERICAN
NLS_LANGUAGE     :AMERICAN
NLS_TERRITORY     :AMERICA
NLS_INSTANCE_PARAMETERS
NLS_DATE_FORMAT     :DD-MON-RR
NLS_DATE_LANGUAGE     :
NLS_LANGUAGE     :american
NLS_TERRITORY     :america
NLS_SESSION_PARAMETERS
NLS_DATE_FORMAT     :DD-MON-RR
NLS_DATE_LANGUAGE     :
NLS_LANGUAGE     :american
NLS_TERRITORY     :america
*2* What about the profile option : ICX_DATE_FORMAT_MASK ? Does it determine the Date Format for Self Service alone or does it impact the date format appearing on Oracle Applications Forms and the actual database also ?
*3* If I use a to_date function in ,say, a pl/sql function that i code for some custom requirements,what will be the output of the date format ? Does it take the format given in NLS paramaters or is it determined by anything else?
Thanks in advance...

Hi,
Thanks for your reply ,but I'm still confused ..
Here are the profile options I'm seeing for one of my instance :
ICX: Date format mask - 12/31/1999
ICX: Date language - American English
ICX: Language - American English
ICX: NLS Sort - BINARY
ICX: Territory - United States
ICX: Numeric characters - NULL
NLS parameters are given in my original email.
In Self Service applications(OAF) ,the date format is appearing in "mm/dd/yyyy" format but when i login to Forms based applications ,I see the date format as "dd-mon-yyyy".What determines this date format ?
How can i make the date format to always return one format everywhere ,be it Self Service (OAF) or Oracle Forms ?
I'm getting date format related errors for my code because of default date formats changing intermittently when i log into Self Service.I want to know if there is anyway to prevent this from happening?
Thanks in advance.

Advance Replication and Oracle Label Security

Has anyone been able to configure both Advance Replication and Oracle Label Security to work together?

This is currently not supported in Streams. I have an enhancement request in with Oracle for this functionality. This won't be seen in 11g R2 either.
Has anyone done Label Security with Advance Replication?
